Is it all that dangerous to keep 20 gallons of gas in the back yard?
Is it illegal to trasnsport more than 5 gallons (California) in a car?

Do they have vent holes and/or pour spouts?

They are certified EPA spillproof leakproof kidproof red plastic gasoline
cans. Gas goes in. Never comes out.

The only opening is the spout. It has special "engineering" to not let the
gas out. Gas only develops about 20psi when heated under the hot sun so
that's not enough to blow up the can (http://www.blitzusa.com/faq.htm).

There was a test of the Blitz cans on the web (gotta dig for it) which
showed absolutely zero weight loss (they measure weight not volume) for a
can out in the sun for a year IIRC. When compared to the "vented" can, the
Blitz won.

Of course, it's a B*TC* to get the gasoline OUT of the can, but that's a
whole nother topic.
